A standard quartic potential requires an unphysically small coupling constant to obtain density perturbations in agreement with observational data. Web4 de out. de 2013 · The inflationary model using the SM Higgs boson with the non-minimal coupling ( 1) will be called Higgs inflation (HI). The first step in the analysis of the inflation with the non-minimal coupling is the classical solution of the slow-roll evolution.

Web• Stability of the Higgs effective potential is extremely sensitive to the value of the Higgs and top quark masses. Can obtain a local minima at large field values. Higgs potential as function of Higgs field value, mt=171.8 GeV, mh=125.2, 125.158, 125.1577 GeV • Higgs sitting in this false minima would provide exponential inflation and Web27 de jun. de 2014 · Abstract: Higgs inflation can occur if the Standard Model (SM) is a self-consistent effective field theory up to inflationary scale. This leads to an upper bound on the top Yukawa coupling, y (t) (phys) < y (t) (crit) and thus on the mass of … the case that haunts me season 1 episode 2

Web11 de abr. de 2024 · The aim of this paper is to highlight the challenges and potential gains surrounding a coherent description of physics from the high-energy scales of inflation down to the lower energy scales probed in particle-physics experiments. Webprediction for the Higgs mass range has turned out to be surprisingly compatible with the measurement of a Higgs mass of 125.9 0.4 GeV by the LHC [11,12]. As it is well known, inflation can generate quantum mechanically tensor (gravity wave) modes, usually para-metrized through r, the ratio of tensor-to-scalar perturba-tion spectra at large scales. http://ias.ust.hk/workshop/cosmology/2014/doc/kawai.pdf taunton deane waste collection days
